Zipp 808 NSW 82mm carbon rear wheel for disc brakes, tubeless ready set up with tubeless valve and tape already installed. Shimano freehub body. Freehub needs a service as there is some resistance when freewheeling, cant back pedal. Thought it was the freehub body so installed a new one (£120) but hasn't solved the issue, likely a bike shop will be able to do a freehub service and get it sorted. Will include the old freehub (also shimano) and Zipp cognition oil which is used to maintain the freehub. Very fast wheel used it in a sub 4 hour 70.3 earlier this year, just needs a good service which I haven't got the knowledge or time to do. Open to offers.
